low and above which will afford someillumination to the ground when theplane is at rest. Other objects will appear from time to time throughout the specification and claims.

My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein-' Figure 1 is a plan view; Figure 2 is aside elevation of an airplane showing the lights in place;

Figure 3 is a plan view on an enlarged scale of the light itself;

Figure 4 is a side elevation of the light; Figure 5 is a section along the line 55 of Figure 3;

Figure 6 is a section along the line 6-'6 of Figure 5;

Figure 7 is a section through the globe; Figure 8 is a plan view of a holding ring; Figure 9 is a plan view of the base ring; Figure l0 is a section through a thin wing section showing my light.

Like parts are indicated by like characters throughout the specification and drawings.

A is an airplane of the conventional type having the usual wings A and rudder My light is used by mounting two of them as shown in Figure 1 on opposed sides of the rudder section or by mounting two of them as shown in Figure 2 above and below the wing section or if a very thin wing'section is used or if the light is put at a thin part of the section, it may be used by placing one light only at top and cutting away the back of the wing so that light may be seen from below;

As indicated in Figures 3 to 6 inclusive, the light comprises a binder plate B which is attached to the underside of the tail surface bounding an aperture B disposed in such surface B Mounted on this member 50 B is a lamp socket B held in place by a 1929. Serial No. 344,642.

bridge 13*. This lamp socket is held by means of screws B to a plate 13 integral with the bridge. B is the electric light bulb attached by means of a bayonet joint as indicated at B in the electric light socket. B are the conductors leading out from the socket to any suitable power source.

C is a bowl of glass or other translucent substance reinforced by ribs C and flanged at C to rest upon the surface of the wing or tail fabric. C is a packing ring overlying the flan e C and engaging this packing ring is a locTxing ring or plate C having a flat portion C engaging the wing surface and upwardly flanged at C to engage the packing ring G This member is provided with a series of apertures C having relatively small notches C adapted to engage screws 0* the heads of which are too big to pass through said notches but small enough to pass through the apertures C; By loosening these screws the plate may be moved from one side so that it may be lifted off when the bowl can be removed or replaced.

The underside of the wing surface is cut away in register with the light when it is desired to use but a single light and in that case since the bottom of the bowl is open the light shines through.

In Figure 10, it will be noted that the solid aircraft wing is apertured but the lower side of the aperture is closed by translucent plate D held in a supporting ring D on the underside of the fabric.

I claim:

1. A running light for airplanes and the like comprising a reinforcing ring adapted to engage one side of the plane fabric, a

light source mounted'upon said ring, a bowl adapted to engage the opposed side of the fabric, removable means for holding the bowl in direct contact with the fabric in register with the ring.

2. A running light for airplanes and the like comprising a reinforcing ring adapted to engage one side of the plane fabric, a light source mounted upon said ring, a bowl adapted to engagethe opposed side of the fabric, removable means for holding the bowl in position against the fabric in register with the ring, the removable means comprising a packing gland associated with the bowl and a flanged ring conforming generally to the contourof the first mentioned ring adapted to engage the packing and clamp the bowl in place.

3. A running light for airplanes and the like comprising a reinforcing ring adapted to engage one side of the plane fabric, a light source mounted upon said ring, a bowl adapt ed to engage the opposed side of the fabric, removable means for holding the bowl in position against the fabric in register with the ring, the removable means comprising a packing gland associated with the bowl and a flanged ring conforming generally to the contour of the first mentioned ring adapted to engage the packing and clamp the bowl in place, said second ring being apertured to permit passage of holding screws, the apertures having extension slots small enough to hold the screw head and screws passing through both rings to hold the parts together.

4. In combination with an airplane wing, a light source arranged adjacent one side of the wing, aremovable bowl enclosing the light source on one side, the opposed wing fabric being cut away in register with said bowl to permit light to be seen from the opposed side.

5. A running light for airplanes and the like comprising a reinforcing ring adapted to engage one side of the plane fabric, supporting means carried by the ring, a light source mounted on the supporting means, the supporting means and light source being in part in the plane fabric, a bowl adapted to engage the opposed side of the fabric, re-

movable means for' holding the bowl in position against the fabric in register with the ring and for clamping the fabric between the ring and bowl, the ring being open in a direction opposed to the bowl. Signed at Chicago, county of Cook, and Stateof Illinois, this 28th day of February,

EDWARD A. SIPP.
